AllRock Advances Lung Disease Treatment with Sanofi Drug Acquisition: Targeting Two Severe Pulmonary Conditions with Innovative Approach

AllRock Bio Secures $50 Million to Pioneer New Treatment for Pulmonary Hypertension

Natick, Massachusetts – AllRock Bio, a newly launched biotechnology company, has secured $50 million in Series A funding to accelerate the clinical progress of its lead drug candidate, ROC-101.This innovative therapy aims to address Pulmonary Arterial Hypertension (PAH) and other cardiopulmonary conditions with a unique approach targeting Rho kinases (ROCKs).

A Novel Approach to Cardiopulmonary Disease

Pulmonary hypertension, a serious condition characterized by high blood pressure in the arteries of the lungs, affects millions globally. AllRock’s strategy centers on inhibiting rocks,enzymes crucial in cellular function,and whose overactivity contributes to vascular issues. This approach builds on the success of Rock inhibitors already employed in treating glaucoma, offering a potential breakthrough for lung-related vascular problems.

ROC-101: A First-in-Class Candidate

ROC-101 distinguishes itself by targeting both ROCK1 and ROCK2, offering a multifaceted approach to battling PAH.Unlike many existing therapies that primarily address arterial constriction, ROC-101 has the potential to tackle the underlying causes of the disease, including inflammation, fibrosis, and cell proliferation. This perhaps addresses a crucial gap in current treatments.

From Sanofi Acquisition to New Beginnings

The journey of ROC-101 began with Kadmon Holdings, later acquired by Sanofi in 2021. While Sanofi’s portfolio didn’t align with PAH treatment, the promising preclinical data surrounding ROC-101 caught the attention of Catherine Pearce, CEO of AllRock Bio. Pearce,previously with CinCor Pharma (acquired by AstraZeneca for $1.3 billion),recognized the potential and founded AllRock in 2023 to continue its development.

Promising Phase 1 Results

Initial Phase 1 trials in healthy volunteers have demonstrated ROC-101’s safety and tolerability. The study, involving 90 participants, showed no evidence of hypotension, a primary concern with ROCK inhibition. Detailed findings will be presented at the European Respiratory Society Congress in Amsterdam later this month, offering a closer look at the drug’s pharmacokinetics and target engagement.

Expanding Beyond Pulmonary Arterial Hypertension

allrock is not limiting its focus solely to PAH. The company intends to investigate ROC-101’s efficacy in treating Pulmonary Hypertension with Interstitial Lung Disease (PH-ILD), a condition frequently enough linked to progressive lung disorders. Currently, United Therapeutics’ Tyvasso and Roivant sciences’ Pulmovant are key players in the PH-ILD space, but AllRock aims to differentiate itself with an oral pill formulation.

Comparative Landscape of PAH Treatments

The PAH treatment landscape is evolving. Merck’s recent FDA approval of sotatercept (Winrevair) introduced a new class of drugs targeting the underlying causes of the disease. AllRock envisions ROC-101 as a complementary therapy, enhancing the benefits of existing treatments like winrevair and traditional vasodilators.

treatment	Mechanism of Action	Management
Winrevair (Sotatercept)	Targets proteins linked to pulmonary vessel thickening.	Subcutaneous Injection
Traditional PAH Drugs	Vasodilation (widening of blood vessels)	Oral/Inhaled
ROC-101 (AllRock Bio)	Inhibition of ROCK1 & ROCK2 enzymes.	Oral (Pill)

Did You Know? The concept of targeting ROCK enzymes for cardiovascular disease isn’t new. Fasudil, a pan-ROCK inhibitor, has been used in asia for years to treat cerebral vasospasm, providing a precedent for ROC-101’s potential effectiveness.

Pro Tip: Understanding the nuances of different PAH treatments can empower patients to have informed conversations with their healthcare providers about the best course of action for their individual needs.

The $50 million investment, co-led by Versant Ventures and Westlake BioPartners, reflects confidence in AllRock’s innovative approach and the expertise of its leadership team. The company’s efficient capital utilization, progressing from pre-clinical stages to Phase 2 readiness in just 16 months, makes it a standout in the biotech arena.

Understanding Pulmonary Hypertension

Pulmonary hypertension is a progressive and debilitating condition. Early diagnosis and effective treatment are crucial for managing symptoms and improving patient outcomes. The ongoing research and development of new therapies, like ROC-101, offer hope for individuals affected by this disease. Further development of more effective oral treatments, like ROC-101, could considerably improve quality of life for patients currently relying on injectables
